I have an add-in written for Office pre 2007. It provides some
functionality that is invoked by a toolbar button. The toolbar appears
when the add-in is loaded and goes when it is unloaded.

Now this doesn't work in Office 2007 because the ribbon has replaced
the toolbar. Nevertheless the underlying code works because you can
use the VB editor to manually invoke it.

I have been asked to migrate the add-in to 2007.

I would appreciate some advice on how to change this. What is the
standard to use instead of the toolbar?
